Universes — frequently asked questions

Can I play in multiple universes?
Yes, you can create a separate character in each universe and switch between them. Progress in each universe is kept independently.
Do my achievements carry over when I switch universes?
Each universe has its own progress. Achievements and resources do not transfer between universes, but the global player profile is shared.
How do universes differ besides pace?
Universes differ in development speed, alliance mechanics, resource balance, event frequency, and overall play style. Details are in the comparison table above.
Can I transfer resources or fleet between universes?
No. Each universe is fully isolated. This ensures fair play and equal starting conditions for everyone.
How do I choose a universe if I am unsure?
Start with War of Alliances — our recommended universe for newcomers. You can always try the others later.
Does premium work in all universes?
Yes. One premium covers all three universes at once. This is designed so you can try different play styles without paying twice.
